Brief Summary:
The purpose of this study is to compare the effect of a blood thinning drug called Apixaban versus no administration of a blood thinning drug, in preventing blood clots in children with leukemia or lymphoma. Patients must be receiving chemotherapy, including asparaginase, and have a central line (a catheter inserted for administration of medications and blood sampling)

Condition or disease Intervention/treatment Phase

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 500 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A Phase III Randomized, Open Label, Multi-center Study of the Safety and Efficacy of Apixaban for Thromboembolism Prevention Versus No Systemic Anticoagulant Prophylaxis During Induction Chemotherapy in Children With Newly Diagnosed Acute Lymphoblastic Leukemia (ALL) or Lymphoma (T or B Cell) Treated With Asparaginase
Actual Study Start Date : April 9, 2015
Estimated Primary Completion Date : May 28, 2020
Estimated Study Completion Date : May 28, 2020

Arm Intervention/treatment
Experimental: Apixaban

Children aged 1 to <18 years weighing 6 to <35 kg randomized to apixaban will receive a fixed dose apixaban based on body weight tier twice a day for approximately 28 days.

Children aged 1 to <18 years weighing ≥ 35 kg will receive 2.5 mg of apixaban twice a day for approximately 28 days. Subjects ≥ 5 years may be administered either 2.5-mg, 0.5-mg tablets or oral solution apixaban. Subjects < 5years and < 35 kg may be administered 0.5-mg tablets only

Drug: Apixaban
Placebo Comparator: No systemic anticoagulant prophylaxis
No systemic anticoagulant prophylaxis
Other: No systemic anticoagulant prophylaxis

Primary Outcome Measures :
  1. Efficacy: A composite of adjudicated non-fatal deep vein thrombosis (DVT, including asymptomatic and symptomatic), pulmonary embolism (PE), and cerebral venous sinus thrombosis (CSVT) and venous thromboembolism (VTE)-related-death [ Time Frame: Up to 1 month ]
    Objectively confirmed by independent adjudication

  2. Safety: Adjudicated major bleeding using the International Society on Thrombosis and Haemostasis (ISTH) definition for children [ Time Frame: Up to 1 month ]

Secondary Outcome Measures :
  1. Efficacy: a) Non-fatal asymptomatic DVT [ Time Frame: Up to 1 month ]
  2. Efficacy: b) Non-fatal symptomatic DVT [ Time Frame: Up to 1 month ]
  3. Efficacy: c) Non-fatal PE [ Time Frame: Up to 1 month ]
  4. Efficacy: d) CSVT [ Time Frame: Up to 1 month ]
  5. Efficacy: e) VTE-related-death [ Time Frame: Up to 1 month ]
  6. Safety: Composite of major and clinically relevant non major bleeding (CRNMB) using the ISTH definition for children [ Time Frame: Up to 1 month ]
  7. Pharmacodynamics: Anti-FXa Activity measured by plasma concentration assay [ Time Frame: Up to 1 month ]
  8. Pharmacokinetics: Measured by maximum observed concentration (Cmax) [ Time Frame: Up to 1 month ]
  9. Pharmacokinetics: Measured by trough observed concentration (Cmin) [ Time Frame: Up to 1 month ]
  10. Pharmacokinetics: Measured by area under the concentration-time curve in one dosing interval [AUC(TAU)] [ Time Frame: Up to 1 month ]

  • Renal function < 30% of normal for age and size as determined by the Schwartz formula
  • International normalized ratio (INR) > 1.4 and activated partial thromboplastin time (aPTT) > 3 seconds above the upper limit of normal for age, within 1 week prior to enrollment.
  • History of allergy to apixaban or Factor Xa inhibitors
  • History of significant adverse reaction or major bleeding related adverse reaction to other anticoagulant or antiplatelet agents
  • History of any significant drug allergy (such as anaphylaxis or hepatotoxicity
